Paul, thanks for your answer.
But I need it in another way. I manipulate PDF Elements from an outside application via Javascript (Flex, Javascript via IEXplorer Runtime). To do that, my PDF is injected with an Listener to react for calls from Javascript via postmessage(). Now, I need to prepare a method for returning a datastructure (like your XML mentioned above, but containing all formular elements, e.q. as seen in the hierarchy of LC Designer).
I think the problem can be reduces to Javascript question: how to retrieve data back via javascript, quasi a readData() as counter piece of Javascript's postmessage().
Or, totally different - is there a LC Forms Server Service available which can be used to retrieve the scheme of an XDP-File in the LC repository?
Does anybody has any ideas, for readData or Forms Service?
Regards, Leo
